Evidence of a spectral steepening of the gamma-ray emission from the Galactic center ridge
Very high-energy (VHE) γ-ray emission detected from the central molecular zone (CMZ) hints at diffusive propagation of cosmic rays (CRs) injected continuously near the Galactic center (GC). Using H.E.S.S. VHE γ-ray observations, we aim to construct a multicomponent description of the region in order to derive the spati...
